FYI on Virtual Machine Information integration

Each VM has either 3072 MB of RAM for i686 guest systems or 8192 MB of RAM for x86_64 guest systems as well as two CPU cores allocated for execution and evaluation purposes within an established baseline VM system.

When I have the VMs running with 1536 MB of RAM, I am able to enjoy using VMs for executing my Fedora 9, 10, 11, and 12 systems. With the effective use of VMs, I am able to concurrently run 9 VMs on my workstation. There are three pictures at the bottom of this page:

Some system information

Food for thought

This is a tipMy current workstation has eight (8) x86_64 computing cores and 16 GB of RAM as well as four 500 GB harddisks (SATA Seagate 7200.12.) The Seagate 7200.12, 500 GB harddisk is only "one" platter and is very quiet as well as very low power consumption and fast for my use. I am considering a plan on doing an upgrade to the Seagate 7200.12, 1 TB harddisk next calendar year. Another workstation has arrived with eight (8) x86_64 computing cores and 64 GB of RAM.

This is importantA finding on my behalf regarding concurrent guest operating systems is to keep the ntp time clock in sync between the variety of guest VMs.

This is something else importantFedora 12 Alpha with 3072MB of RAM. After that amount of 3 Gigabytes (GB) RAM, the 32-bit kernel is abending. Also, the "Swap" space is defined about 4 GB.

This is a noteThe Fedora 11 and Fedora 12 Alpha version's "Swap" space are defined about 3 GB, versus the Fedora 9 and 10 versions' "Swap" space are defined about 2 GB when all versions were provided 1.5 GB of RAM.

This is an additional noteAt this time, I am not really very impressed with the dracut product. The dracut execution time was about 15-25 minutes to update my kernels dependent on the virtual machine being used. As of September 22nd, 2009, I have used dracut about 40+ times. Maybe when the F12 Beta and/or F12 Final Release are made, dracut will be better. Update, with F12 Beta and RCs, the dracut execution time is now about 2-3 minutes.

This is a warningA little FYI on updating to the 2.6.31-2.fc12.i686 and 2.6.31-2.fc12.i686.PAE kernels, a separate rpm install was needed of the bindutils-2.19.51.0.14-31.fc12.i686.rpm package from the original install media's iso, in order to address the bindutils dependency prior to updating to the 2.6.31-2.fc12.i686 and 2.6.31-2.fc12.i686.PAE kernels.

This is a cautionCurrently, the Virtual PC 6.0.156.0 and the F12 Alpha iso are having some serious problems with getting X to work. Therefore, my /etc/inittab file on those test subsystems is set to run at runlevel 3 instead of 5.
